SPECIFICATION forming part of Letters Patent No. 788,162, dated April25, 1905.

Application filed April 23, 1904- To (477 [Ff/(Hit it may concern:

Be it known that I, ARTHUR L. Ma'rnuwscw, a citizen of the UnitedStates, residing at Norwich, in the county of New London and State ofConnecticut, have invented new and useful Improvements in SpinningMechanism, of which the following is a specification.

.\ly invention pertains to spinning mechan- 1 ism designed to take theplace of spindles in spinning-machines; and it contemplates theprovision of a spinning mechanism adapted to run as light and at as highspeed as any spindle extant and one which makes two twists to onerevolution, whereby its capacity is increased and power saved, and inwhich the bobbin rotates only fast enough to take up the material asdelivered by the roll and rotates slower as it loads with material, soas to lessen the atmospheric pressure against it, and hence the powernecessary to drive it.

Other advantageous features of the invention will be fully understoodfrom the following description and claims, when taken in connection withthe accompanying drawings, forming part of this specification, in which-Figure l is a front elevation of the spinning mechanism constituting thepresent and preferred embodiment of my invention. Fig. 2 is a verticalcentral section of the same, taken at right angles to Fig. 1. Fig. 3 isa view illustrating the spindle and its appurtenances as removed fromthe frame and with some of the appurtenances separated. Fig. l is adetail sectional view illustrating the top support for the spindle. Fig.4 is a view taken at right angles to Fig. A and illustrating one of thedepending arms of the said support. Fig. 5 is a detail sectional viewofthe spindle and its zwpurtenances. Fig. (5 is a detail plan view of thedevice designed to be con nected with the bobbin-builder of aspinningframe and to move up and down to build the bobbin. Fig. T is adetail view of the lower portion of the upright shaft which carries saiddevice and the spring for rocking the 1 shaft in one direction.

broken perspective view of the idler, showing the swinging piece, whichis carried by said idler, as extending therefrom.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which M A is a frame which may be of anyconstruction compatible with the purposes of my invention.

I3 is a material-holding spool loosely mounted on a fixed spindle r/ atthe top of the frame and subjected to the pressure of a spring I), so asto prevent it from turning too freely.

U C are rolls journaled in the upper part of the frame and arranged toreceive between them the material from spool B.

.l) a material-guide, preferably an eye, which is arranged below thefront roll U.

E is an arm connected to the upper portion of the frame A and having abifurcation 1 in its forward end and also having alined notches (l inthe upper and lower walls of said bifurcation, and F is the topsupportfor the spindle hereinafter described. The said top support comprises astem journaled in the bifurcated portion of the arm E and having asocketf in its lower end and a pin extending diametrically across saidsocket, and also having a disk /1, interposed between the walls of thebifurcation c, and a groove 1, adapted to be registered with the notchesl for a purpose prcsently described, and diverging arms A, connected tothe stem 0 below the arm E.

The diverging arm j differs from the arm Z: in that it is provided inone of its side edges with a notch /and has at its lower end anoutturned portion 11/, notched, as indicated by v).

(1, Figs. 1 and 2, is a drum journaled in the lower portion of the frameA and having upon one of its trunnions a pinion 2. H is a gear mountedon a short shaft I], connected to the frame A and intermeshed with thepinion p; l, a pulley fixed on the gear ll; J K, pulleys lixed togetherand loosely mounted on a shaft 1', connected to the frame A; L, a beltconnectingthe pulleys l and J, and M a belt connecting the pulley IQ andthe frontroll C. .In virtue of this construction it will be observedthat when the drum G is rotated in the direction indicated by arrow inFig. 2 by any suitable means the front roll C will be rotated in theopposite direction, so as to take material from the spool B after themanner shown in Fig. 2.

N, Figs. 1 and 2, is a vertically-movable lever fulcrumed ate in thelower portion of the frame A and having a free longitudinally-slottedportion 25.

P is a finger-lever fulcrumed at in the base of the frame A and havingan upwardly-directed toe v; movable in the slot of the lever N andprovided below said lever with lateral lugs 10; Q, a vertical shaftjournaled in horizontal portions 00 1 of the frame A and provided at itsupper end with a material-carrier V R; S, a whirl feathered on the shaftQ and disposed above the frame portion :12, and T a crossed beltconnecting the said whirl and the drum G. Through the medium of thecrossed belt T and the whirl S the material-carrier R is rotated in thedirection indicated by arrow in Fig. 1 to carry the thread around thelower end of the idler presently described, and yet said carrier may beadjusted vertically to permit of the idler, the spindle, and the partsthereon being readily removed from the apparatus. The material-carrieris normally held in the position shown in Fig. 2 through the medium ofthe lever N, in which the lower end of the shaft Q is stepped, and thefinger-lever P, and when it is desired to lower the said carrier it issimply necessary to throw the finger-lever P in the direction indicatedby the arrow at the left of Fig. 2. As best shown in Fig. 3 of thedrawings, the saidmaterial-carrierR comprises acup-shaped body .2,having a notch a in its side, arms Z c reaching outwardly and upwardlyfrom the upper edge of the body 2, and a horizontallydisposed cam (Zfixed with respect to the lower portion of the body a. The outwardly andupwardly reaching arm cdifiers from the arm Z) in that it has a lateralprojection (Z of circular form in cross-section provided in its outerside with a groove (Z U, Figs. 1 to 3 and 5, is an idler, whichconstitutes an important feature of my mechanism, as will presentlyappear. The said idler comprises a horizontallydisposed disk-like body 0and a central reduced portion f", of circular form in cross-section,depending from the body a and designed to loosely rest in the cup-shapedbody .2 of the material-carrier B after the manner illustrated in Figs.1 and 2. Said depending portion f has a bifurcation in its lower end, inwhich is pivoted on a pin 2 a swinging piece g, having a materialguidinggroove 2", while in the upper portion of the idler is a socket 7",designed to receive the spindle presently described, which has acircumferential groove in its lower portion, Fig. 5, to receive a screwk, by which it is held against upward movement out of the socket and yetis permitted to turn freely in the idler and with respect thereto. Whilethe depending portion f of the idler U and the piece g in said portion frest in the cup-shaped body 2 of the material-carrier R the said idlerU, as its name implies, does not revolve.

Reaching upwardly from the perimeter of the circular or disk-like body fof the idler U is a bar Z, which is provided in the outer side of itslower portion with a material-guiding groove m, Fig. 3. On the upper endof the said bar Z an arm n is removably secured through the medium of athreaded bolt 39' on the arm, which bolt extends through a notch q inthe upper end of the bar, and a nut 7 mounted on the bolt and arrangedto bear against the outer side of the bar Z. The arm n has avertically-disposed aperture .9, designed to receive the spindle,presently described, at a point above the bobbin, and when the idler,the spindle and bobbin thereon, and the bar Z and its appurtenances areremoved from the apparatus the said arm it may be readily disconnectedfrom'the bar Z, so as to permit of the quick and easy removal of thebobbin from the spindle. When desirable, the arm 91 may have a verticalnotch in its lower end to receive a stud on the inner side of the bar Z,Fig. 2, this to hold the said arm it against swinging laterally on thebar Z.

V, Figs. 2 and 5, is the spindle comprised in my novel mechanism. Theupper end of the said spindle is let into the socketf of the top supportF and is provided with a notch which receives the diametrical pin 9 ofthe top support, whereby it will be seen that when the spindle isrotated the top support will be caused to rotate with it. As beforestated, the lower end of the spindle is arranged to rotate in the socket7" of the idler U, and immediately above the disk-like body 0 of thesaid idler and integral therewith is an eccentric 25. (Best shown inFig. 5.) This eccentric t is disposed in a circular aperture in ahorizontally-movable plate a, provided with a projection o, and isdesigned to move the said plate so that the projection 1; thereofalternately rests within the outline of the idlerbody a and projectsbeyond the said outline this in order to enable the projection to clearthe material, as presently more fully described. The plate M is furtherprovided with a projection o carrying an upwardly-extending lug w, whichrests in a notch w of a plate .2 on the spindle, and has for its purposeto transmit rotary motion from the said plate a to the spindle. Theplate 2 is preferably fixed on the spindle through the medium of aset-screw 2", which preferably takes into a recess 2 in the spindle,Fig. 5.

l/V is the bobbin, which is removably placed on the spindle V below thearm n"; X, a block loosely mounted on the upwardly-extending portion ofthe plate u and arranged in the lower enlarged portion of the bobbin; Z,a collar loosely mounted on the spindle and arranged to bear against thebobbin, and A a coiled spring surrounding the spindle and interposedbetween the block X and the collar Z. The said spring serves to pressthe collar Z against the bobbin and holds the bobbin under yieldingpressure against the arm 22,, with the result that suflicient tension isprovided between the spindle and the bobbin to assure the bobbin takingup just the quantity of material which the front wall C delivers.

B is a slide movable vertically on the bar and held against casual ortoo free movement on said bar by a spring Fig. 52. and C is a fingercarried by the said slide, curved in the direction of its length anddesigned to serve a purpose set forth in the following description ofthe operation.

I) is an upright rock-shaft journaled in suitable bearings in the frameA and having a lateral arm E on its lower portion provided with one ormore depending lugs 71* and also having an upper portion c of angularform in cross-section; E, a coiled spring mounted on the lower portionof the rock-shaft D and having one of its arms connected to the frame Aand its other arm connected to the shaft arm B, so as to hold the lug Ifon said shaftarm in position to be engaged by the edge of the cam (1,and F is a piece mov: ble vertically on the angular upper portion of theshaft l) and arranged to rock with said shaft and having fingers fdesigned to serve the purpose set forth in the following description ofthe manner in which the mechanism operates.

The swinging piece is provided in the lower portion of the idler U inorder to facilitate the threading of the idler, the said swinging piecebeing extended from the idler when the thread is placed in the groove1". Fig. 11, and being then returned to its normal position in theidler. (Shown in Figs. 3 and In practice my novel mechanism is threadedafter the manner shown in Figs. 1 and 2 that is to say, the material ispassed first between the two rolls C, then through the eye I), thenthrough the notch Z in the disk it of the top support F, then throughthe notch and notch 12 of the support-arm j, then down between thelingers of the device F, which has for its function to move and buildthe bobbin, then through the groove in the swinging piece of the idlerU, then through the notch 1/ in the cup-shaped body of the carrier R.then up and over the projection of the carrier-arm c, where it rests inthe groove (1*, and then up and over the linger (,7 and to and aroundthe bobbin. \Vith this done the drum G is rotated in the directionindicated by arrow in Fig. 2, when the material will be delivered by therolls 0 and twisted on the bobbin \Y. The placing of the material in thegroove of the swinging piece may obviously be readily effected when thesaid piece is swung so as to carry the groove out of the bifurcation inthe reduced depending portion of the idler U, as shown in Fig.

11 and before described The twistingof the material on the bobbin isacciinnplished in the following manner, viz: The belt T and the pulley Stransmit rotary motion to the carrier R, and the said carrier by reasonof its arms w being arranged to engage the projection r of theeccentric-plate a and the lug *w on said plate a resting in the notch.1" of the plate .2, fixed on the spindle V, serves to rotate the saidspindle. As one of the arms 6 c passes out of engagement with theprojection r of plate a the other arm engages said projection, and fromthis it follows that the spindle will be kept in perfect motion. Theside of the carrier R being notched, as indicated by a, the said carrieroperates to push the material before it and carry the same around thelower end of the idler, and thereby makes two twists to one revolution,which contributes materially to the capacity of the mechanism. The endof the plate 1/ bearing the projection r is alternately moved outwardlyand inwardly through the medium of the eccentric f, fixed on the upperside of the idler U, and hence it will be seen that the said projectionr will clear the material incident to the rotations of the spindle andbob bin thereon. The cam d, which is fixed with respect to the carrierit. as before described, engages one of the lugs 0 of the arm E on shaftD in the direction indicated by arrow in Fig. 2 to assist in buildingthe bobbin through the medium of the device F. The said device F is freeto move vertically on the upper portion of the shaft l), and the slide Bis adapted to be moved vertically on the bar *arried by the idler U.

It will be appreciated from the foregoing that the idler U does notrevolve, and yet holds the material or thread and conveys the same tothe bobbin, and at the same time as sists materially in the control ofthe material or thread. It will also be appreciated that the bobbinnever makes more than about three hundred turns per minute to about sixthousand turns of the spindle, and hence the at mospheric pressureagainst the bobbin is lessened. This is particularly true when thebobbin is loaded with material, since the speed of the bobbin graduallydiminishes as the material is put upon the same, and hence but a minimumamount of power is necessary to drive the bobbin.

The device F connects with the bobbinbuilder of a spinning-frame andmoves up and down to build the bobbin. The said bobbin-builder and theconnection between the device F and the same form no part of myinvention. and l. have therefore deemed it unnecessary to illustrate thesame. The said device F also serves to hold the idler U against rotationand to move with the shaft 1) and act upon the slide B after the mannerof a pallet-lever in the scape-wheel of a watch or clock movement. Onefinger of the device F holds the idler U while the thread passes by, andas soon as thread passes one finger of the device F that finger takesits place in the slide B,while the thread passes the other fingerwithout interruption. The device F is also intended to rest under theshelf on the outer side of the slide B and move the slide up and down onthe bar and hold the idler U against rotation and move out of the way tolet the thread pass by. This latter is due to the cam cl and the arm E.The finger C on slide B lies fiat against the bobbin when the latter isempty and moves outwardly as the bobbin fills up, this to lay the workon the bobbin. The thread is carried up from the groove m and passesover finger C and on the bobbin. From this it follows that the work iscarried up and down to build the bobbin, the idler U is held still tomake the two twists, and the work is laid on the bobbin.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a definite understandingof the construction, mode of operation, and advantages of the saidembodiment.
